How does gender and occupational prestige affect credibility?Graduate students in a public health program are asked to rate thestrength of a paper about the health risks of childhood obesity. Inreality, all student raters are given the same paper, but the nameand degree associated with the author are changed. The studentraters are randomly assigned to one group from the following name("John Lake", "Joan Lake") and degree (M.D., R.N., Ph.D.)combination. The raters score the paper from 1 to 5 on clarity,strength of argument, and thoroughness. The total scores (the sumof the three scores) are given in the table below. What can beconcluded with an ? of 0.05?

John Lake / M.D.	John Lake / R.N.	John Lake / Ph.D.	Joan Lake / M.D.	Joan Lake / R.N.	Joan Lake / Ph.D.
12 15 13 15 14	15 16 12 13 13	11 8 13 12 9	15 10 12 14 12	10 7 8 10 6	11 11 12 8 8

a) What is the appropriate test statistic?
---Select--- na one-way ANOVA within-subjects ANOVA two-wayANOVA

b) Compute the appropriate test statistic(s) tomake a decision about H₀.
Name: p-value =  ;Decision:  ---Select--- Reject H0 Fail to reject H0
Degree: p-value =  ;Decision:  ---Select--- Reject H0 Fail to reject H0
Interaction: p-value =  ;Decision:  ---Select--- Reject H0 Fail to reject H0


c) Compute the corresponding effect size(s) andindicate magnitude(s).
Name: ?²=  ;  ---Select--- na trivial effect smalleffect medium effect large effect
Degree: ?²=  ;  ---Select--- na trivial effect smalleffect medium effect large effect
Interaction: ?²=  ;  ---Select--- na trivial effect smalleffect medium effect large effect


d) Make an interpretation based on theresults.

There is a name difference in the total scores.There is no namedifference in the total scores.    

There is a degree difference in the total scores.There is nodegree difference in the total scores.    

There is a name by degree interaction in the total scores.Thereis no name by degree interaction in the totalscores.
